Other Languages/Term like "boyfriend"

QuestionI'm looking for a term for boyfriend, such as
"He's my boyfriend," not for a term of
endearment one would call another.
But I'm looking for something more along the
lines of what mature adults who are not yet
engaged/married would use, rather than the
sort of casual, young relationship which
"boyfriend" implies.

AnswerDear Caren,
When someone is your 'خواستگار', he has proposed marriage to you and you have not yet decided whether you are going to accept or not. Once you said yes, he is still your 'خواستگار' until you become engaged ('نامزد'). But it does not usually take so long when a 'خواستگار' becomes a 'نامزد' in Persian culture.
Otherwise, he is your 'دوست پسر' no matter how old and mature any of you are, especially when there is no intention or commitment for marriage.
Living in a same house and having a life together without having it legalized is not historically such a common way of being into a relationship in Persian culture. The relationship itself is called 'ازدواج سفید'. Although there is no specific name for what one would call another in such a relationship, you may use 'هم خانه' and 'دوست' when you want to refer to that.
Apart from this, not every relationship can be named neither in Persian nor in any other language. As for the term 'complicated' in English, people may have unique stories in their lives and may never be able to introduce them by names.
Hope this helps, Mojtaba Parsa

Expertise

As you may know, Persian culture is one of the most ancient cultures in the world. This enormous volume of antiquity has always been affected by different cultures through the passage of history: National beliefs, language, religion, borders, etc. I can answer you about Persian culture before and after Islam - which is known as a milestone in Iranian history, and also about the various languages spoken by Iranians, and give you translations in today's Iran's official language, Farsi (Persian). I have a full access to Iranian books, scripts and antique artistic industries. For those of you who are interested in having a valuable Persian piece of text or art, this is the rightest place to be.
Sincerely, Mojtaba
